The present invention relates to an antibody composition and its application. The antibody composition can specifically recognize SARS-CoV-2 RBD protein, SARS-CoV-2N protein and influenza virus HA protein, and the present invention utilizes the antibody composition to prepare test paper, and the test paper includes a liner, a sample pad, a gold Standard binding pad, nitrocellulose membrane and water-absorbing pad, the sample pad, gold standard binding pad, nitrocellulose membrane and water-absorbing pad are sequentially overlapped and bonded on the liner, and the test paper can simultaneously detect SARS-CoV- 2 virus and influenza virus, and simultaneously target the nucleoprotein (N protein) of SARS-CoV-2 and the RBD region of Spike protein (RBD protein) to improve the sensitivity and specificity of SARS-CoV-2 virus detection. |
